Easy ascii vault boy ascii art4/8/2024 ![]() But the fact is that this doesn't happen often in real life, so using the two separate methods will still be a better option.īut then, you could always implement both ways and choose the correct way depending on the original vs. Of course, you may argue that if somebody wants to resize a small image to a larger one and then transform it, the above situation will be reversed. Therefore, it is better to resize it first before transforming it, hence the two separate methods given above. If you use the merged method, you will need to transform the entire image before the resizing takes place. To illustrate this, consider the case where you want to resize a HUGE image down to a small size and then convert it to ASCII Art. However, there is a catch in using the above merged method. Graphics g = Graphics.FromImage (newImage) Use Graphics object to draw the resized and // transformed image onto the bitmap. TransformData.SetColorMatrix (CreateColorMatrix( Rectangle imageArea = new Rectangle ( 0, 0, Create an empty bitmap with the new size. The merged version will look like the following: ![]() Now, at this stage, you may be wondering whether we can merge Step 3 and 4 together (assuming you use the second resizing method above), the short answer is: yes. G.DrawImage (resizeImage, imageArea, imageArea.X, Graphics g = Graphics.FromImage (transformedImage) ImageAttributes transformData = new ImageAttributes() ĬreateColorMatrix (brightness, contrast, saturation)) Set up the image transformation parameters. New Rectangle ( 0, 0, resizedImage.Width, New Bitmap (resizedImage.Width, resizedImage.Height) Create yet another new image for // the color transformation. public GetTransformedImage (Image resizedImage, NOTE3: The implementation of the CreateColorMatrix() // method will be discussed later. = 0.0 or above, 0 = total white, // 1 = original, higher = darker // // NOTE2: hue is not implemented in this version. = 0.0 or above, 0 = grayscale, // 1 = original (colors), // higher = very 'colorful' // gamma = extra brightness correction to picture. = 0.0 or above, 0 = complete gray, // 1 = original, higher = glaring white // saturation = The amount of 'grayscale-ness' // in picture. = -1.0 to 1.0, -1 = pitch-black, // 0 = original, 1 = total white // contrast = Amount of difference between red, // green, and blue colors. NOTE1: brightness = Amount of 'sunlight' in picture. The page will display the correct user account that ASP.NET is running under. To find out exactly what account your IIS is using, just copy and paste the following code into Notepad and save it as who.aspx, then put the file into a web-folder under IIS and view it in Internet Explorer. Note: On some machines (especially servers), IIS doesn't actually use the ASPNET account to run ASP.NET pages. Also, give read/write permissions to the following (local) user accounts for the Images sub-folder (residing under ASCII sub-folder):.After that, give read permissions to the following (local) user accounts for the ASCII sub-folder:.Next, make a virtual directory in IIS that links to the ASCII sub-folder mentioned above.First, unzip the files to an empty directory.Library - A library (DLL) for generating ASCII Art.ASCII - An ASP.NET web page that demonstrates the ASCII Art generator functionality.In the source files included above, you will find the following two Visual Studio projects: NET.įor the list of web sites from where I got all my ideas/information, or if you just want to know more about ASCII Art in general, please check out the References section given below. What I did was I searched through the web, found some web sites with image-to-ASCII conversion applications in PHP, combined all their ideas (including Daniel's), and implemented another (more enhanced) version of the ASCII Art generator in. This is yet another article on the same topic, but with a slightly more enhanced ASCII Art generation. According to Daniel, he was not able to find any C# application on the web that does image-to-ASCII conversions, so he decided to write his own, and hence his article. Well, a few months ago, I stumbled across an article 4 on Code Project by Daniel Fisher which talks about creating an application that does just this. Have you ever seen a C# application that converts a given image to a text-based ASCII Art image like the ones shown above? ** The Windows application port is provided by David Luu, and is not maintained by me.ĪSCII Art image (colored and monochrome) ĪSCII Art image (pure color-HTML and unformatted text-only) Introduction Download demo Windows App source files** - 64.3 KB.Download demo web-application - 26.4 kB.
